When ph decreases the hydrogen ion concentration increases because ph = - log (H)
Likewise, the other way around is true (when hydrogen ion concentration increases, pH decreases).
Fission is the energetic splitting of large atoms such as Uranium or Plutonium into two smaller atoms, called fission products. To split an atom, you have to hit it with a neutron.
Hope this helped.
Answer:
the 4s subshell is lower in energy than the 3d subshell
Explanation:
In the element number 24 which is chromium
the electronic configuration should be according to Aufbau principle
will be =
but in reality it is =
The 6 electrons in the outermost shell will be divided as 5 in 3d subshell and 1 in 4s shell, because half filled orbital will be more stable than .
Dry air is a mixture of nitrogen, oxygen, carbon dioxide etc.
air is a mixture of gases 78% nitrogen an 21% oxygen and other components.
Beacause of lack of force in all three scenarios.
In scenario one there’s two forces acting in the bottle atmospheric pressure and gravity.Gravity keeps the ball at the lowest pointwithout force resisting it.
Umber two there’s no other force greater than gravity that would cause movement to the apple..
And number three there are isn’t any force acting in the rubber band greater than the elastic force to make it stretch
